We look at the division of 947051 by 87 
The aim is to understand the frequency of 87 in 947051.

Let's proceed to step 1:
87 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 87

Advancing to step 2:
When dividing 94 by 87, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 87 away from 94, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 87

Going ahead to step 3:
87 can be fit into 77 0 times, resulting in a remainder of 77.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 77 and we're left with 77.
Take the next digit (0) from the dividend and append it to 77, then repeat: 770 / 87

On to step 4:
If we divide 770 by 87, we get 8 and a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 108.0
Subtract 696 from 770 to get 74.
Take the next digit (5) from the dividend and append it to 74, then repeat: 745 / 87

Let's proceed to step 5:
The number 87 fits into 745 8 times, leaving a remainder of 49.
The number 8 becomes the next digit in our result. 
Result so far: 1088.0
If we subtract 696 from 745, we get 49.
Take the next digit (1) from the dividend and append it to 49, then repeat: 491 / 87

Advancing to step 6:
The number 87 fits into 491 5 times, leaving a remainder of 56.
Write down 5 as next digit of the result. 
Result so far: 10885.0
If we subtract 435 from 491, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 7:
When dividing 560 by 87, we get 6 with a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 10885.6
If we take 522 away from 560, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
87 goes into 380 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 10885.64
Subtract 348 from 380 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
320 divided by 87 is 3 with a remainder of 59.
The number 3 becomes the next digit in our result. 
Result so far: 10885.643
The remainder is 59 after subtracting 261 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 10:
If we divide 590 by 87, we get 6 and a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 10885.6436
If we subtract 522 from 590, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 11:
The number 87 fits into 680 7 times, leaving a remainder of 71.
The next digit of our result is 7. 
Result so far: 10885.64367
If we take 609 away from 680, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 12:
If we divide 710 by 87, we get 8 and a remainder of 14.
The next digit of our result is 8. 
Result so far: 10885.643678
If we subtract 696 from 710, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
If we divide 140 by 87, we get 1 and a remainder of 53.
The next digit of our result is 1. 
Result so far: 10885.6436781
Subtract 87 from 140 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 14:
87 goes into 530 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 10885.64367816
Subtracting 522 from 530 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 10885.64367816 with a remainder of 8e-09.
